我有双 Geforce GT1030，带 4 个显示器。我试图启用所有 4 个显示器，这样我就可以在扩展显示器显示中使用它们。
我运行了 sudo add-apt-repository ppa:graphics-drivers/ppa，并选择了 nvidia-384.111、390.25 和 387.34，无论哪种情况，我更改的那一刻：选项“Xinerama”的“0”从 0 更改为 1 并重新启动，屏幕启动，我得到紫色屏幕，然后变黑。黑色就像显示器是活的一样（我可以看到光标），但没有 ubuntu 会话或登录屏幕。
在 384.111 上，我在 gdm3 配置下完全禁用了 Wayland，以查看是否存在问题，但似乎没有改变任何东西（nvidia 驱动程序似乎默认会这样做？）。
以下是我的 xorg.conf，可供参考：

答案1
最终，当启用 Xinerama 时，Unity/Gnome3 与双 GT1030 发生了冲突，至于具体原因我并不清楚，但当我切换欢迎程序和显示管理器时似乎取得了进展，所以我的解决办法是完全切换到 Xubuntu，这不仅解决了我的问题，而且似乎可以正常工作，并且运行得非常好。
